Article Suggestion: “Provide Contextual Information in Log Messages”

Leider ist der Eintrag nur auf English verfügbar.Software developer Tom Hombergs recently wrote an article about making log statements more useful by providing context in order to make it easier for a developer who uses your libraries or builds upon your code to find out what the actual cause of an error is. The blog post contains many pertinent examples of both good and bad log output. Seemingly trivial improvements such as making your log output more helpful and explicit can make a ...

On Writing Unmaintainable Code

Leider ist der Eintrag nur auf English verfügbar.Software developer Andrew Yurisich maintains an - ironically - maintainable version of the authoritative guide to unmaintainable code by Roedy Green of Canadian Mind Products. This expansive, tongue-in-cheek how-to teaches developers to make themselves indispensable through writing code only they can understand. Aside from the comical value learning by what not to do can be an extremely useful method. By making sure your code follows none of the guidelines put forward in this how-to you'll already ...

Use Boring Solutions

Leider ist der Eintrag nur auf English verfügbar.Often when working with both startups and project teams at larger, more seasoned companies I encounter a variation of the not invented here syndrome. This usually starts with the well-intentioned idea that in order to build the actual product you need ancillary services A, B and C in order for the product to work. However, more often than not instead of building the 'perfect' solution for your product yourself it might be a good idea to ...

One Cannot Not Design

Leider ist der Eintrag nur auf English verfügbar.One cannot not communicate. - Paul Watzlawick Philosopher and communication theorist Paul Watzlawick famously stated as one of his five axioms of group homoeostasis (the ability of a system to maintain its current state or equilibrium) that "one cannot not communicate", meaning that it's impossible to completely avoid communication. Even the act of intentionally not communicating - by staying silent for example - is an act of communication. In the case of silence depending on the ...

Paying for Developer Tools

Leider ist der Eintrag nur auf English verfügbar.Recently, a user named amerkhalid wrote this on Hacker News (commenting on a question about the market for developer tools): Agreed. Developers are hard bunch to sell to. We go out of our way to find free tools and almost look down on people who use decent IDEs or other tools. One example, when I finally got legit license for Sublime Text, all of my friends made fun of me for paying for a free ...

More on JSON and REST API Specifications

Leider ist der Eintrag nur auf English verfügbar.Expanding on my previous posts about annotating and validating JSON data structure with JSON Schema defining and documenting REST APIs using Swagger I have two additional suggestions for tools that help you define and build HTTP-based APIs in a less haphazard, more deliberate manner: JSON API: While JSON Schema allows you to annotate and validate JSON-based data types JSON API gives you clear, opinionated guidelines for structuring JSON API responses so you don't have think about those implementation ...
